The interfacial structure of nano-and micron-sized oil and water droplets stabilized with SDS and Span80

Sylvie Roke, Esther Amstad, Nikolay Smolentsev, Evangelia Zdrali, Gianluca Nicolas Etienne

In this work, we provide a comparison between the stability and the interfacial structure of micrometer-sized and nanometer-sized droplets by employing a multi-instrumental approach comprised of the surface-sensitive technique of sum frequency scattering a ...

Heat-transfer at the interface between a metal and a non-metal: influence of ultra-thin interlayers, interface chemistry and atomic order

Maïté Blank

The Thermal Boundary Conductance (TBC) at the interface between metals and dielectrics is of key importance for heat transport in structures heterogeneous on a scale from 100 µm downwards. In this thesis the TBC of a large number of metal/dielectric couple ...

Cast aluminium single crystals cross the threshold from bulk to size-dependent stochastic plasticity

Andreas Mortensen, William Curtin, Csilla Mikó, Jérôme Krebs, Suzanne Godelieve Alphonsine Verheyden, Satish I Rao

Metals are known to exhibit mechanical behaviour at the nanoscale different to bulk samples. This transition typically initiates at the micrometre scale, yet existing techniques to produce micrometre-sized samples often introduce artefacts that can influen ...

On-chip NIR optical spectrometer based on polymeric waveguide and metallic nano-structures

Hans Peter Herzig, Toralf Scharf, Maurine Malak Karam Awadallah

In this work, we report about optical spectrometry using gold nano-structures printed on a polymer based integrated optical waveguide. The optical waveguide is a single mode buried waveguide, having dimensions of 3x2.2µm 2 . It is made from a combination o ...

Microchannel Flow Boiling Heat Transfer, Update on the Latest Experimental and Numerical Contributions

John Richard Thome, Mirco Magnini, Sylwia Szczukiewicz

The scope of the present paper is to provide a brief and concise survey of the most recent experimental and computational studies aimed at characterizing local heat transfer in microchannels in flow boiling conditions. The significant developments in the m ...

Optical reconstruction of transparent objects with phase-only SLMs

Christian Depeursinge, Yves Delacrétaz, Cristian Arfire

Three approaches for visualization of transparent micro-objects from holographic data using phase-only SLMs are described. The objects are silicon micro-lenses captured in the near infrared by means of digital holographic microscopy and a simulated weakly ...

Several micron-range measurements with sub-nanometric resolution by the use of dual-wavelength digital holography and vertical scanning

Christian Depeursinge, Tristan Colomb, Jonas Kühn

Reflection digital holographic microscopy (DHM) is a very powerful technique allowing measuring topography with a sub-nanometer axial resolution from a single hologram acquisition. But as most of interferometer methods, the vertical range is limited to hal ...

Epitaxial Lead Chalcogenides on Si for Mid-IR Detectors and Emitters Including Cavities

Niels Quack

Lead chalcogenide (IV-VI narrow-gap semiconductor) layers on Si or BaF2(111) substrates are employed to realize two mid-infrared optoelectronic devices for the first time. A tunable resonant cavity enhanced detector is realized by employing a movable mirro ...

Micro-Four-Point probe based on SU-8 cantilevers

Stephan Keller

The four-point probe is used for the measurement of the resistivity of thin metal or semiconductor films. There is an interest in miniaturization of the probes to obtain higher surface sensitivity, an increased spatial resolution and less damage to the sam ...
